I maintain two FTP servers which running on Windows Server 2008 R2 and Xlight FTP Server. Each server has 1Gbit bandwidth to our company's network backbone.
Recently, FTP Service is more unstable because higher load than before. I want to add one more server to resolve the problem while I do not have confident to maintain three servers like that.
And I can't find a good way to distribute file access load to three servers equally. Now I use ftp logs to do that work by manually moving files between two servers according their access rates.
My servers serve big files which more than 100MB like media files. I find a distributed FTP server called DrFTPd which based on Java. After several days I set it up but have many problems.
Do I need a distributed file server solution to solve my problem? If I need, which one will be better?
Thanks.
